GHURN Application filed April 8,

To all whom z't may concern: Be it known that I, FRANK J. MA'rHnws a citizen of the United States, residing at DeerIPark, in the county of St. Croix and State ofNVisconsin, have invented new and useful Improvements in Churn Timers, of whichthe followingis a specification.

This invention relates to timing devices for use in connection with a cylinder mountedfor rotation and'controlled by a clutch mechanism, the device being especially adaptedfor use in connection with churns," for the purpose "of automatically stopping their operationjafter a predetermined number of revolutions. 7

Another object of the invention is to provide a device of the above character which is capable of adjustment so that the number of revolutions of the cylinder may be regu lated to suit various conditions. Another objectlis the provision of a device which may be used in connection with 'mechanism irrespective ofthe direction of operation of the controlling clutch lever, rendering the device applicable to churns of'diiferent makes.

. Other, objects. and advantages of the invention will appear as the description is read in connection with the accompanying drawings.

In thedrawings:

Figure 1 is a side elevation of one end of a churn cylinder with the invention applied thereto and showing an operating mechanism in which the clutch lever operates in a direction toward the churn cylinder tostop the operation of the churn.

Figure 2 is an enlarged elevation of the invention removed from the churn and looking in a direction at right angles to Figure 1.

Figure 3 is a sectional view taken on a line with the tensioning device.

Figure 4 is a view similar to Figure 1, illustrating the invention applied to a churn, whose clutch lever operates in a reverse direction to that shown in Figure 1.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the reference character 10 denotes a cylinder of a churn, which is mounted to revolve horizontally through the medium of suitable operating mechanism, the said mechanism being controlled by a clutch lever 11. This lever Figure 1 is movable in a direction toward the cylin- DEER PARK, WISCONSIN.

.der 10 to release or stop the mechanism and in an opposite dlrection to throw 1n a clutch 15, between which is mounted for rotation a spool 16. This spool is mounted upon a short shaft 17 and carries at one end a toothed wheel 18. The wheel 18 is positioned at right angles to and slightly spaced from the end wall of the cylinder 10 and-is located in the path of movement of a projection 19, herein shown in the form of an L-shaped finger secured to the end wall of the cylinder 10. p Secured to the opposite end of the spool 16, is a ratchet wheel 20, the teeth of which are adapted to be engaged by a spring detent 21, secured upon the frame 13. This ratchet wheel and detent serve to limit the degree of rotation of the spool 16 at each engagement of -the projection 19 with the toothed wheel 18. The spool 16 is connected to the clutch lever 11 through the medium of a flexible element 22, the latter being in the form of a cord or chain, having one end connected to the spool and its opposite end connected to the said clutch lever, so that when the flexible element has been sufficient- .ly wound upon the spool, a pull will be that after a predetermined number of revolutions of the cylinder 10, the flexible element will become taut and a pull exerted upon the lever 11 and the rotation of the cylinder discontinued. In order that the flexible element may be properly wound upon the spool, the frame 13 supports a tensioning device in the form of an arm 23, one end of which is secured to the said frame and the opposite end of which is formed into a spring clamp 24, which is adapted to yieldingly hold the flexible element taut between the tensioning device and the spool. Guide flanges 25 are provided upon the opposite side edges of the clamp I d changes injit s "form,

applied to a churn mechanism, the con trolling lever 26 of which operates in 'a di-'- rection reverse to that of the lever ll previously described, or in other words is moved in a direction away from the cylinder 10 to stop the operation of the churn. To accomplish this the fiexibleelement which connects the lever and spool is threaded through a pulley 27,the latter .being" ad justably mounted upon an arm 28, as shown at 29. This arm is secured to the frame of the churn, as shown at 30. The spool" 16, may therefore be rotated in the same direction as the one previously described. The pull upon the inner portion of the flexible element 22 is exerted in a direction toward the end of the churn, while the pull upon the outer end or the end connected to the lever 26, is exerted in an opposite directiomfl or away from the end of the churn. 7

In this form of the invention the frame of the timing mechanism differs slightly from the frame 13, previously described. This difference resides in providing asubstantially L-shaped frame 31, one end of which is bifurcated and'supports the spool 16 in the usual manner and the opposite end is connected to the frame of the'churn,

as shown at 32.

It will be apparent that the functions of the various parts of the invention are simi lar in both forms shown, the changes being mere matter of details to adapt the invention to different makes of churn.
